37 Claims.

My invention relates to multiple-billing mechanism for typevvriting machines, and has for its general object the provision of a new and improved machine for handling multiicrm billing sheets of the character disclosed in the patent to Z. Lewis, No. 932,713, dated August 31, 196e, which sheets, interleaved with a reproducing medium, are wound on the platen of the machine, one complete wind or wrap being allotted to each separate iorin on the sheet, so that the number of forms to be printed at a single operation corresponds with the number oi times the sheet is wound or wrapped on the platen. The carrying out or my invention in practicable form has resulted in various detail improvements relating to the feed and control oi the multiiorm worlr sheet or iorm sheet i self, the supplying, feeding and control of the re reducing medium or carbon sheet, and various safety devices for insuring the proper cooperation of inter-related parts, all as will hereinater appear.

This application is a division of myA application Serial No. 183,466, iiled April 13, 1927 and is directed more particularly to:

(1) Means 'for locking the platen controlling means against actuation except when the carriage properly registers with the magazine from which the work sheets are supplied.

(2) Means for affording various adjustments ci the magazine.

(3) Means for preventing a continuous rotation or" the platen except when it is in the desired rotative position to begin a line of writing.

(4) Mears for controlling a work sheet as it is fed to and from the platen.

(5) Means for folding a worl; sheet as it is delivered from the platen, and to other details of the construction which will hereinafter appear.

To the above ends my present invention consists in the features of cons ruction, combinations oi devices and arrangements of parts hereinafter described and particularly pointed out in the appended claims.

The principle or my invention will be found adapted to various styles of writing machines, but the preferred form of the invention, as illustrated in the accompanying drawings, has been applied to a #20 Remington typewriting machine.

in the drawings:

At all of the section lines arrows indicate the direction in which the view is taken.

Only so much of the machine is shown in the Various views as is necessary to illustrate the features of the present invention in their embodiment therein.

Referring first generally to the embodiment ci the invention herein disclosed, there is mounted on standards projecting upward from the stand on which the machine is supported, a magazine or box adapted to contain a supply of multiplesheets or work sheets.

in the present instance each one of these sep arate sheets contains six printed forms or blanks, the sheets being folded transversely between each two of the forms. The forms are adapted to be withdrawn from the magazine by hand, one

by one, and introduced into the machine over a table or guide plate to a platen-ca1ried clamp which at this time is at the iront side or the platen, so that they may be iront-fed thereover.

Normally lying between the open clamp and the tace of the platen is the free end of a reproducing sheet or carbon strip which is supy plied from a carbon carrying roll whichis connected by gearing to special platen turning mechanism operative by a handle. Said handle is connected by gearing to the platen and is curate introduo cation.

As shown in l the magazine or holder l Which is preferably made of sheet metal, is provided With cut-outs, and is in what may be termed skeleton form for the salie of lightness. The magazine has a top cover 2 hinged at 3 at the rear and has a front Wall consisting of two plates Ll between which is left a vertical central opening through which the operator may grasp the forms one at a time and withdraw them from the top of the magazine, the loosely hinged cover yielding or being lifted the purpose. The upright side portions 5 of the magazine are formed with vertical guide sic-ts 51 which receive the end portions of a metal bar 6 which serves as a weight to rest on the pi c r stack of folded multiple bill forms 7 within the magazine. It will be understood that the rod may yield or move upward in its gi de slots whenever a bill sheet 7 is withdrawn from the magasine, Knobs 8, secured to the projec end portions of the rod 6, prevent its accidental endwise withdrawal.

The bottom of the mag sine has secured to it near its ends a pair or" clamping blocks 9 (see Fie. 8) which are secured by screws l0 to a cross bar 11. This provides a bodily tilting adjustment of the magasine as well an adjustment of it aiong the supporting rod li. Said rod 1l is mounted in cla g blocks l2 held in their position of vertical adjustment by clamping screws 13 to pair o uprights or le that rise from rear portion of a frame or stand l5 (Fi i) on which the typewiting machine is supp rted. This stand may be of ordinary construction but the uprights le have been added thereto to provide a support for the maganne.

It will be observed that the mounting such that the magazine is adjustable sidewise, may be given a tilting adju and receive a bodily on the uprignts le. provided with cross one 16 is shoe/'n in E provided with seche or the type The main r ne of said chine comprises a base portion 19 from which i. i posts 20 supporting a top plate 2l. i ing from the top plate, as shown in Figs. i, E and are front and rear lugs 22 and 23 siectively which are screwed stationa y rai or track way-fs 24 and 25 respectiv ly. These track ways are oppositely grooved and receive antifricticn rollers 26 which also 1ate with tle iront rear cross bars 2'? and ry oi a carriage truck which further com ses right and lefthand side ba "s numbered rernpeetively 29 and 3 A bracket arm 3l l to the top of the truck at i i ha corner :ls connected a oa the usual carriage rector or si eling carriage, corn gether 'with the is constantly urged ieitwar 24 and 25.

In carrying out my invention provide a new style or construction of pieten carried clamp; also a new port; a carbon roll ejecting means and other dov or controlling these elements, all niet ted on the truck or carriage, although certain only ci features are claimed herein. To provide mountds of which the forward said cr ss rod being l? to receive the feet 1S .g ma ine.

common to the #2O le or supthe trackways cwriting inapaper these ings for these parts, supplementary end plates are mounted on the carriage truck. The right and left-hand end plates numbered respectively 33 and 34 are secured respectively to the outer face of the end bars 29 and 3G by means of screws and dowel pins 35 (Figs. 1, 2 and 3). The platen, indicated as a whole by the reference numeral 35, is in the form of a hollow shell or tube preferably made of aluminum. Said platen, as best shown in Figs. 3 and 5, comprises a tubular body portion 37 to which are secured heads or end pieces, the righthand head being numbered 38 and the left-hand head 39. These are i duced at their inner ends to fit inside the tube 37 and are secured in place by screws 40. The heads 38 and 39 are provided respectively with outwardly extending' hub portions 41 and 42 which are bored out to receive a platen shaft or axle 43, the hub 42 being secured to said shaft by a screw 42a. At its right-hand end portion, the axle bears in an enlargement or hub 44 which is fixed in the end plate 33. The left-hand end portion of the axle 43 an enlargement or hub 45 secured in the end plate 34. The portion of the axle projecting leftward beyond the bearing 45 carries a nge wheel 46 of ordinary construction for turning the platen by hl ad, which wheel is secured in place by se screws 47. The outer end portion of the hub 42 reduced in diameter and has suitably secured to it a gear wheel 48 for positively connecting the platen with paper feeding devices hereinafter described. The hub portion 4l, of the right-hand platen head, is extended outward and formed with teeth 49 to provide a pinion that inter-meshes with platen driving mechanism hereinafter described.

Driven or forced on the pinion so as to have a tight fit therewith hub or bearing element 50 (Fig. 3) to which is nxed a line spacing ratchet wheel 5l, the wheel 5l and the part 50 being secured togetherl and acting as a unitary member, which in turn is fast on the hub 41, 49 and consequently rigid with the platen 36. The flanged portion 52 of the ratchet wheel member 50, 51 provides a bearing for the hub portion 53 of a pawl carrier 54, the parts 53 and 54 constituting the pawl carrying r. ein. er being united and adapted to turn freely on t e Bange 52. At its lower end the pawl carrier 54 carries an outwardly projecting pin 55 over which is hooked a spring 56, which at its rear end is anchored to a suitable b acket. rlhis spring assists in restoring the lii e space train to nor-n mal position after operation.

The pawl carrier 53, 54 has pivoted to its upward extension a line spacing pawl of ordinary construction, which adapted to coaot with the ratchet wheel 51. Said pawl is connected by suitable means to a hand controlled actuating lever 68 (Fig. l) by which the line spacing pawl may be actuated in the usual manner as in left-hand line spacing devices employed in Remington machines and as fully disclosed in my hereinbefore mentioned application Serial No. 183,465.

Cooperating with the ratchet wheel 5l is a roll detent 72 (Fig. 3) which mounted at the forward end of a arm .73 that extends rearward and is secured by a screw to a projection that is integral with the bracket 3l. The spring mounted roll-detent when effective cooperates in the usual manner with the line space ratchet wheel.

In addition to the mechanism just described for turning the platen through line space distances, means are provided for turning the platen continuously through a plurality of revolutions, said means comprising speed-multiplying mechanism, next to be described. Intermeshing with the pinion 49 is a driving gear wheel of comparatively large diameter, which is illustrated in Fig. 3, and which is of ordinary construction, comprising a rim provided with spur gear teeth 75, radial spokes 76 and a hub portion 77. Said hub extends outward and bears at its outer end against a circumferential enlargement on a supporting sleeve or hub 73 which is riveted or otherwise fixed to the end plate 33. The supporting sleeve 73 bored to receive and provide a bearing for the shaft 36. For the purpose of actuating the stub shaft a crank member or handle is provided comprising a crank arm 99, a hub 100, and a handle proper or nger piece 101. The hub is fitted over the projecting portion of the shaft 86, outside the end plate 33, and is secured to the shaft by a cross pin 102.

At this point it may be well to explain that there are provided intermediate actuating connections between the shaft 36 and the gear wheel 75-77 involving a lost motion connection that enables said shaft and its crank 99-191 to be given a limited preliminary movement independently of said gear wheel and the platen which is controlled thereby. lt may also be explained that there are adjustable stop means for arresting the rotation of the gear wheel 75-77 in opposite directions, all as disclosed in my hereinbefore mentioned application of which this case is a division and in which prior application the features referred to are claimed. Inasmuch as a specific detailed description of these features are unnecessary to an understanding of the present invention such description will be omitted and it will be sufficient to understand that rotative motion is transmitted from the crank 99-101 to the gear 75-77 and from the latter through the pinion 49 to the platen and that such motion in both directions is limited.

Preferably, the driver or gear wheel 75-77 is provided with a circular shaped guard or cover plate 123 which is made of sheet metal and is provided with a flange to overlie the periphery The cover plate is provided with of the wheel. enlargements or bosses 124 (Fig. l) which receive headed screws 125 whereby the coverplate is secured to the side-plate 33 of the carriage frame. The cover-plate is disposed inside the plate 33 and spaced leftward therefrom by the bosses 124 so that said cover-plate is brought into the vertical plane of the gear wheel which it covers.

Referring now brieily to the automatic paper clamp which is mounted on the platen, and having reference to Fig. 5, the tubular platen body 37 is cast with an inwardly projecting rib-like part or enlargement 37fL in which is cut a slot-way 126 which extends longitudinally of the platen and receives the bar-like or body portion 127 of the clamp which is adapted to slide radially in and out of the slot-way 125.

fea lo.,

Said clamp further comprises a clamping flange or lip 123 which is formed integrally with the body or bar 127 and projects rearward at right angles from said body outside the platen surface, to which the outer face of the lip is curved to conform. The inside or working face y of the lip 123 is straight or iiat and nts against the corresponding flat surface of an under-cut or depression 129 in the tube 37. The construction is such that when the clamp is closed it hugs the platen tightly and provides an uninterrupted surface, as will be clearly apparent from Fig. 5. Of course, when the paper is inserted between the coacting flat clamping face 129 and the under face of the lip 128, the clamp will be projected outward slightly away from the platen surface, but not sufficiently to alter materially the regular continuity of the surface and the smoothness of the rotation of the platen will not be affected.

Means, not shown herein but fully disclosed in my hereinbefore mentioned parent application where such means are claimed, are employed for automatically opening and closing said clamp. However, since a specific disclosure of these means are unnecessary for a clear understanding of the features of the present case, such means will not be referred to in detail eX- cept to point out that the clamp is automatically controlled, so that it is opened to receive the Work-sheet at the end of the rearward worksheet ejecting movement of the handle 101, and thereafter is automatically snapped shut by the preliminary forward actuation of the handle 191, so as to clamp the paper to the platen before the winding-on operation starts.

It will be apparent that during the windingon of the bill sheet, it will be positively connected to the platen and caused to be wrapped around the same primarily through the paper clamp 127, 128. After the bill has been written,

A: however, and it is desired to eject it rapidly,

the clamp is of no assistance, and accordingly there have been provided feeding devices which are thrown into effective position and positively connected to the platen automatically i when the platen approaches theV end of the winding-on operation, so that the feeding devices may cooperate with the bill to advance it during line spacing operations and also during the subsequent continuous ejecting operation.

As shown in Figs. 1, 2, 3 and 5, the paper feeding devices comprise knurled metal rolls 172 xedly secured one near each end of a shaft 173 which extends longitudinally of the platen above the printing line, the rolls being so disposed as to cooperate with the face of the platen near its The shaft 173 is mounted near its ends on a of downward curving arms 174 which at their lower ends are provided with outwardly extending collars 175 which t over and are iixedly secured to a rock shaft 176 which bears at its ends in the plates 33 and 34 of the carriage frame. Crank arms 177 upstanding from the collars 175 are formed with holes through which are hooked the forward ends of draw springs 178. The rear end of the left hand spring is anchored to a pin 178a (see Fig. 5) projecting inward from the side plate 34, while the rear end of the right end of the right-hand spring 178 is anchored to an arm 58IL integral with a bracket sec red to the carriage, as shown in Fig. 2. The springs tend constantly to swing the shaft 176 a direction which will press the feed rolls 172 into engagement with the surface of the platen. Mounted on the left-hand end of the shaft 173, outside the arm 174, is a pinion 180 (Fig. 5) which lies in the same fore-and-aft plane as the gear L18 and is adapted to intermesh therewith when the feed rolls 172 engage with the surface of the platen or the paper thereon. The construction is such that the feed roll shaft 173 is positively connected with the platen through the gear 48 and pinion 180, so that when the platen is turned, it will positively turn the feed or pressure rolls 172, causing them to coact to feed 01 advance the paper passing between them.

In order to lock the feed rolls 172 out of operation during the Winding-on of the bill when they would be superfluous, means are provided comprising lugs 181 extending outward from the arms 174 and adapted to be engaged by hooks or arms 182 which extend rearward from and are secured to a rock shaft 183 that bears in angular brackets 184 secured by screws 185 to the front part of the carriage. A spring 183a coiled around the rock shaft and acting thereon, tends constantly to press the hooks or arms 182 downward.

The operation of the means for automatically controlling the paper feeding mechanism is as follows:-When the clamp 127, 128 is open to receive the work sheet it will act against the feed rolls 172 to force them away from the surface of the platen and cause the hooks 182 to snap down over the lugs 181 which will operate to maintain the feed rolls in inoperative position during the subsequent winding-on of the bill. As the end of this winding-on approaches means which it is unnecessary to disclose herein are employed for automatically releasing the feed roller from control of the locking arms 182. The parts are so timed that this operation takes place approximately at the end of the windingon operation.

One of what may be called the safety devices incorporated in the machine, and which forms part of the present invention, comprises means for preventing the billing mechanism from being operated in a direction to wind on a bill sheet unless such bill sheet has been actually clamped in place on the platen. The means aforesaid comprise, as shown in Figs. 2, 3, and 5, an arm 188 provided with a hub 189 which fits over and bears on a rod or shaft 190, said shaft being secured in a tubular support or nut-like member 191 which cooperates with a screw 192 to maintain the parts in xed relationship with the end plate 34. The rod projects inward from the end plate and underlies the platen near its left-hand end. A collar 193 is secured to the right-hand end of the rod 198 and has anchored to it a wire spring 194 which is coiled around the rod and is connected to the arm 188, tending constantly to draw the forward end of said arm upward. Said forward end terminates in a tooth or pawl 1832t which registers with a depression 195 (Fig. 2) formed in the left-hand end portion ofthe platen surface. The outer or free end of the arm 188 carries is rotatably mounted a roller 196 which is adapted to ride on the surface of the platen, it being constantly pressed there-against by the spring 194. The roller 198 is also adapted to engage with the depression 195, and the conl struction is such that if there is no paper in the machine, the roller riding down in the depression 195 will permit the pawl or detent tooth 188 to engage with the edge of said depression after the platen has been only slightly turned in winding-on direction, such engagement positively arresting the platen and preventing operation of the mechanism. 1t will be further understood that when a bill sheet has been clamped to the platen, it will bridge or cover a pin 196d on which over the depression 195 therein so that the roller 196 will not drop into said depression. Thus the pawl will be held out of engagement with said depression when the platen is turned, and will be ineiective to lock the mechanism against operation.

As has been hereinbefore pointed out a sheet of reproducing material or carbon paper 197, ordinarily supplied in roll form is automatically interwound with the bill sheet as the latter is wound on the platen, and is automatically wound off the platen and back on the carbon roll carrier as the completely written bill sheet is wound off the platen and ejected therefrom in folded form. The mechanism including the carbon roll carrier and the means by which it is operatively connected with and controlled from the platen for the purpose stated above is claimed in a separate divisional application filed June 16th, 1928, Serial No. 285,884. Such mechanism is unnecessary for the purpose of arriving at an understanding of the present invention and has not been shown in detail in the accompanying drawings, nor is any detail descrip ion of it herein deemed necessary.

The forward end portions of the bracket arms 151 (see Fig. 5) are twisted vertically and terminate in head-like portions l5lfL and there are ears 278 bent down from the end portions of a guide plate 279 which rests on pins 289 projecting inward from the heads 151e. The guide plate 279 serves to receive and support the free end portion of the carbon paper 197 it passes downward and forward from between the roll holder and the feed roll not shown. -e parts are so adjusted that when the carbon rewinds on the roll holder during the operation of the machine, the end portion of the carbon is left so that it will lie in position to fall into or just baci; of the space between the clamp 128 and the coacting surface 129 when the clamp is opened to receive the work sheet. This will be best understood from a consideration oi' Fig. Y5.

The work sheet 7 having been, as heretofore stated, withdrawn at its feeding-in end portion from the 1 is led down to the platen over pa er guiding devices which constitute in effect a chute and comprise an inclined sheet metal plate or table designated as a whole by the numeral 281. The body portion or plate 282 of the table is of a width to accommodate the sheets commonly employed in practice. Mounted on the upper face of the body or plate proper 282 are side guides or plates 288 of which the right-hand one has lugs 284 projecting downwar through cross slots 285 which hold the right-hand guide 288 in proper vertical position. Said guide is provided with horizontal eX- tensions which receive clamping screws 287 that are adapted to slots in the plate 282 and alford adjustments of the right-hand plate 283 towards and away from the left-hand guide plate 288, so as to provide the correct width for the passage of the work sheet as it is guided downward. Said sheet in its downward course posses between the upper face of the plate 282 and guide members designated as a whole each by the numeral said guide members being formed of sheet metal and being divided by vertical parallel cuts 289 into fingers 299 which at their lower ends are adapted to engage loosely in cross depressions 291. The nger portions 290 are shown as riveted to the body portions, but it will be understood that if desired the parts 288 may be unitary. Secured to the upper curved portions of the bodies 288 and extending over and down behind the same are supplementary ingers 292 which press lightly against the face of the plate 282. rThe whole construction is designed to guide the down-coming work sheet or form lightly and evenly over the table 281. So guided the lower end portion of the sheet will brought into position to be engaged by the clamp 127, 128 when it is opened to receive an end of the sheet. The table member 28l rests normally at its lower end on the inclined faces 276 of the brackets 151, 151e. The paper table as a whole is pivotally supported on a cross rod or shaft 287 and to this end is provided at its rear side with bearing blocks or projections 293 which terminate in outwardly veX- tending hubs 291i (see Fig. 6) which iit over said rod and over end pieces 295 which prevent lateral displacement of the paper table on its pivotal support. The end pieces 295 and hubs 294 are held rigidly united to turn on the shaft 267 by screws 295e. Said table is normally held in operative position by means of detent members 296 rigid with said end pieces and formed with notches 297 and 298 to accommodate detents 299 mounted at the ends of a roclr shaft 300 pivoted in the end plates 33 and 34. Normally the detents 299 engage with the notches 297, holding the table in operative position. A coiled spring 891 (Fig. 2) holds the detents in engaging position. The right-hand detent 299 is provided with a finger piece 302 whereby the detents may be withdrawn from the notches 297, permitting the paper table to be thrown back about its pivotal axis, the detent notches 298 engaging with the detents to hold the paper table in its thrown-off position, thus exposing the underlying mechanism. The rear sides of the notches 298 are so shaped that the paper table may be pulled forward to restore it to normal position without requiring any manipulation of the detente 299 through the controlling finger piece 302.

Y rThe paper table 281 also provides guiding devices for receiving the work sheet 7 after it has been written and as it is fed oil the platen during the continuous ejeoting movement thereof. Said devices comprise the curved upper end portions 2889 of the members 288 which act to receive the top edge of the sheet as it is fed upward. The upwardly advancing edge of the sheet is guided to these curved portions 288SL by guide plates 893 secured to the lower side edges of the plate 282 and extending inward therefrom, said plates 303 being olf-set forward to provide a receiving opening indicated in Fig. 5 by the numeral 804. Integral with the guide plates 393 are upwardly extending fingers 305 which are so shaped as when the upwardly advancing paper is received by the curved guides 288e and thence directed downward, it will be caught by 'these lingers 305 and directed downward to the root portions S thereof and thence again directed upward. 1t will be recalled that the work forms 7 are creased or folded crosswise between blanlrs. rihe receiving and guiding devices, comprising the parts 288e, 395 and 396 are so disposed and shaped that they will automatically fold the feeding-out work-sheet along these creases so that when it is released from CII the curved parts 288a and the upper ends of the fingers 305.

Finally, safety devices have been provided in accordance with my present invention which will lock the mechanism against operation unless the carriage has been moved to the limit of its righthand travel, in which position it will be in accurate register with the stationary magazine l. This an important feature, since if it were possible to operate the winding-on mechanism when it was not in exact register with the paper as it was brought down from the magazine, there would be an inevitable tendency to feed crookedly, resulting in the irregular winding-on that is commonly referred to as spiraling. The safety devices referred to are shown clearly in Figs. 1, 2, 3, 4 and 5. These comprise a cap 367 which fits loosely over the outwardly projecting boss 44 and is secured to and in fixed relationship with the outer end portion of the platen axle or shaft 43 by a shoulder screw 308. The shouldered portion of this screw is square or hexagonal and fits in a corresponding hole in the cap, so that the cap is forced to rotate with the shaft 43. The cap is formed with an integral radial extension, arm of finger portion 309 which is adapted to coact with a notch 31() formed in the upper rear end portion of an arm 311 which extends forward outside the end plate 33 and is secured to the outwardly extending end portion of a short rock shaft 312 which extends inward through the end bar 29 and bears rotatably therein.

Fixed to the inner end of said rock shaft inside the end bar is a hub 313 (see Fig. 4) having a projecting nose 314 which is adapted to be engaged by the right-hand end portion of a pivoted plate 315. Said plate is provided with upward extensions 316 which are secured in the stiffening rod 317, the rod and plate being disposed behind and longitudinally of the front bar 27 of the carriage. The extensions 316 are provided with outwardly extending lugs 318 which bear in perforated ears 319 depending from the angular brackets 184. The plate 315 is adapted to be actuated by a finger or extension 320 which is secured by rivets 320a to a pivot arm 321, which is part of the regular line locking train of a #2O Remington typewriting machine and is adapted to be turned pivotally under certain conditions.

The margin stops 322 are of the usual construction and need not be described in detail. The stationary stop 323 has a pivot 324 and is provided with a downwardly extending nger 325 which operatively engages with the pivoted member 321. The stop 323 is connected through the fingers 325 with the member 321 in such a way that when the stop is turned on its pivot 324, the member 321 will be turned on its pivot. 1n the present case the stop 323 is thus turned automatically during the rightward movement of the carriage. For this purpose the usual carnage-carrier margin stop 326, which is adjustable along the front bar of the carriage in a manner well understood, is provided with a special incline or cam face 32da (Fig. 5) which is adapted to coact with the upper arm cf the frame stop 323. The adjustable carriage stop 326 during the rightward movement of the carriage will engage at its cam 0r beveled face 326L with the stop 323 and exerting a cam action thereon will swing its upper end portion forward, the finger 325 being moved rearward and acting on the member 321 which will cause the extension 320 to swing the plate 315 rearward on its pivots 318. As the plate is swung rearward its right-hand end portion acting against the nose 314 will rock the shaft 312 and swing the arm 311 downward so that the notch 310 therein will disengage from the arm or ringer 309, thus releasing the platen shaft 43 so the platen may be turned. It will be understood that at all times other than when the stops 323 and 326 are operatively engaged at the end of the right-ward movement of the carriage, the locking arm 311 will be maintained up in operative position. This is due to a constantly acting flat spring 327 which underlies the end bar 29 and is secured thereto by screws 328. Said spring has an outwardly extending end portion 329 which underlies the arm 311 and tends constantly to swing it upward. It is only when this spring is overcome by the ccacting carriage stops 323 and 326 in the manner described that the locking arm 311 is swung down to its non-working position.

The various features of the operation of the present invention have been explained and discussed in connection with the description of some of the different mechanisms which coact therewith, and it is thought therefore that a further detailed lengthy description of the mode of operation is unnecessary. It will bc understood that in making use of the multiple-billing mechanism constituting the invention the operator rst pushes the carriage to the extreme right-hand position causing the stops 323 and 326 to coact to arrest the carriage, said stops also effecting a downward throw of the locking arm 311, thus freeing the lnger 309 so that the platen may be rotated. As a result the paper guiding devices on the carriage or traveling paper carrying device are registered with or in line with the magazine, stationary supply device or source of supply 1, so that the tcp bill sheet 7 in the pile of folded sheets in the magazine or source of supply may be brought down from said magazine as heretofore explained and introduced through the chute, that is, over the paper table 281, passing under the guide fingers 290, and being brought into position with the lower or bottom edge of tie multiple-bill shee 7 in position to be gripped by the platen clamp. As has been explained, the free end of thev carbon 197 overlying the guide plate 239 behind the table 281 will have its free end in line with the free end of the bill sheet and behind the same. rEhe clamp 127, 123 will then be opened through the cooperation of the parts, has

been explained. Assuming that the cla-:np 127, 128 is open and in the position shown in Fig. 5, the free ends of the bill and carbon sheets may be introduced between the clamp and the platen face, and then thchandle is pulled forward, giving a continuous rotation to the platen sufficient to rotate it in the present instance through approximately six revolutions so as to ind six plies of the paper with the interleaved carbon around the platen. During this continuous rotation the paper feeding rolls 172 will be out of operation, and will be restored to operative position only at the end of the platen rotating movement. The platen when arrested will present the outer bill sheet in position to have the rst line thereon written. As is well understood the writing will take place through the actuation of the usual printing instrumentalities and ribbon mechanism of the standard Remington machine not herein disclosed but of regular construction. As the first line is Written the carriage will, with the parts mounted thereon, space leftivard step-by-step under the con trol f the usual escapement devices not herein shown, and when the end of the line is reached, the c1 iage Will be restored from left to right and the platen line spaced, by actuation of the line space lever 68. The second and subsequent lines are thereafter Written, the platen being line spaced in between, all as heretofore explained. t will be understood that each character Written on the outer ply of the sheet through the ribbon will be duplicated on each of the five underlying bill forms or blanks through the carbon paper or transfer material 19'?. The Writing of the bill having been completed, the carriage will be restored from left to right and the handle 161, when actuated, will turn the platen forward continuously to eject the bill. This ejection will be assisted by the pressure rolls 172. At the same time that the platen is operating to eject the bill, the carbon roll holder will be turned to rewind. the carbon paper the een. fis the bill sheet is retracted, it Will be received in the receiving guide or paper holder comprising the parts 288g and 305 in folded form. As has been described the platen clamp opens automatically to release the written bill sheet which may then be removed, the outward releasing action of the clamp also operating to throw olf the pressure rolls 172 and lock them in inoperative position.

The operation above outlined may be repeated with each bill sheet. it will be understood that in Writing a bi the tabulating mechanism and other devices associated With the Remington typewriting machine may be employed at convenience.
